To expand on advice given:

US prices will be lower than UK prices. Just get on the web and look up whatever you have in mind. Go to the following sites:

http://www.elby.de/CloneCD/english/ in resoect of CloneCD
http://www.goldenhawk.com in respect of CDRWin

These are the two essential copy programs for PS2 duplication.

Then choose a burner that is compatible with both pieces of software, and DAO+96 is necessary for taking sub-channel information.

I have Yamaha 2100S (SCSI) which matches the criteria (needs a SCSI card). If you choose an EIDE model, place the device on the secondary IDEchannel otherwise you can get buffer underruns and multiple coasters as you fail to provide data from the hard drive to the slower CD burner.

Hope that helps to sort you out
